Kelli is running a mile in gym class. she runs at a pace of 6 minutes per mile. represent this situation with an equation. define d as the distance that kelli has run and t as the number of minutes passed. a. d = 6t b. t = 6 + d c. t = 6d d. d = 6 + t

answer : t= 6d

Kelli is running a mile in gym. She runs at a pace of 6 minutes per mile.

We change the speed to miles per minute

6 minutes per mile = 1/6 miles per minute

d is the distance that Kelli has run and t is the number of minutes passed.

Speed is 1/6   mile per minute

We know the formula distance = speed * time

distance is d, speed is 1/6 and time is t

So the equation becomes

Multiply by 6 on both sides

6d = t

t= 6d

the solution is h=10 because you add 9 to each side of the equation.
